02Density altitude and turboprop runway margins

Standard temperature at 591 ft is about 14°C. Every 1,000 ft of density altitude adds roughly 8 percent to a turboprop's takeoff distance and 5 percent to its landing distance. The table uses Piper Meridian book numbers (2,438 ft takeoff and 2,110 ft landing over a 50 ft obstacle at sea level, ISA, max weight) as a reference airplane; heavier turboprops and light jets scale the same way from their own POH figures.

Conditions	Density altitude	Takeoff est.	Landing est.	Landing × 1.5
Standard day (ISA, 14°C)	591 ft	2,553 ft	2,172 ft	3,259 ft
Warm day (ISA +10)	1,791 ft	2,787 ft	2,299 ft	3,448 ft
Hot day (ISA +20)	2,991 ft	3,021 ft	2,426 ft	3,638 ft
35°C afternoon	3,133 ft	3,049 ft	2,441 ft	3,661 ft

Planning aid only. Even on a 35°C afternoon the longest runway (12/30, 8,859 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,661 ft needed). The percentages are a generic rule of thumb applied to one reference airplane, not certified performance data for any specific aircraft, and the runway size categories describe the runway, not your airplane's suitability. Verify with the approved flight manual before every flight.

03Nearby fields with 5,000 ft or more

Useful as alternates, as fuel stops when the price at KGYY is high, or as the longer runway on a hot afternoon.
